I first saw Kappius Components tricked out and drilled carbon hubs at the North American Handmade Bicycle Show (NAHBS) two months ago in Sacramento. I saw the hubs on a Kent Eriksen creation and they definitely caught my attention. It is easy to pass off these drilled hubs as pet project by somebody who was a bit too enthusiastic in their quest for light weight.

But after talking with Russell Kappius at Sea Otter today, he explains that these hubs are a product of 4 years of R&D. Another thing I learned about Kappius is that basically the whole company races. Russell himself loves racing and comes from an engineering background. He is the owner and inventor of Kappius Components and although the hubs were indeed initially created as a cosmetic compliment, they have some real and tangible benefits and features.

The most attention grabbing feature is the amazing 240 points of engagement that these hubs boast. At more than double the closest competitor, how does Kappius achieve this? He uses 60 teeth, 8 pawls, those pawls act in pairs, so 4 pair, the pairs engage at a quarter tooth, so every every quarter tooth turn, you get engagement. Kappius hubs feature a 1 and half degree scalar angle of engagement vs. 3 degrees on other brands.

What does this all mean to you, the rider? It means the most instant engagement you will find. Instant engagement, maximum power.

Hub Specs:
  • Available for road (130) or mountain bikes(135, 142)
  • Wide bearing spacing: Stiffer front end giving you better control
  • ABEC-5 Double Seal bearings standard, Hybrid Ceramic and Full Ceramic upgrades available
  • Type 3 Black Anodization: Highest wear performance, Rockwell 60C hardness, Smooth surface and deepest coloring
  • Secondary surface coating (gold look on relieved areas) offers 60x corrosion resistance
  • Relieved carbon center offers no differential pressure in the hub. Differential pressure can result in bearing seal permeation due to an air pressure differential between the inside and outside of the hub from temperature and atmospheric changes.
  • Large flange size results in a stiffer wheel
  • Weight: ~110 grams
Offered in 28 and 32 hole configurations for Left, 9mm QR and 15mm QR forks.

Mtbr is looking forward to getting a set of these hubs in for testing soon, so stay tuned.
